Accessing Dynamically Created Labels - ASP.NET?

Apr 28, 2009

My current project involves displaying questions/answers from two different databases to be used to compare values and make judgements. The number of questions, choices, and answers is all variable. Thus I am attempting to create labels dynamically to show the information on the screen and create textboxes to leave comments. My problem is not knowing how to then access these lables, since I can't code in to use "label_comments" & (i) as it doesn't exist (at least, I can't get it to work).

First, my code for creating and displaying the information:

db_connection = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionStringMerrill3"))
db_connection.Open()

Accessing Controls Created Dynamically In Another Procedure?

I'm having trouble trying to access a list of comboboxes created dynamically in one procedure from another. I believe I have to add in an event handler but I not sure how this is going to work. Or should I change the array scope?

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

VS 2008 Accessing Dynamically Created Picturebox?

Mar 22, 2012

For school and other reasons, i am making an application in which the user can draw tile based backgrounds, to then turn into long line of code , i think called CSV , which can then be used in programs such as flash, to draw a tile based background. I am currently making a flash game, and dont really like the other tile array making programs out there.

For instance, code such as [1,0,1],[0,1,0],[1,0,1] with the correct code would generate a 3x3 tile background with an X shape.Anyway, at the moment i am currently stuck.I have code up and running which generates a 2 dimensional background out of pictureboxes randomly, however thats as far as i got, i dont know how to access the pictureboxes created.

What i have right now is two variables, gridX and gridY, which determine the amount of tiles placed in a for loop. These variables would be used to determine the size of multidimensional arrays that store the tile data, and determine the map size.i intended each image to be clickable, so that its picture would change from black to white when clicked

When clicked, the tile would switch between two images, to represent two different tiles. at the same time, a value in an array created with the tile, would change from 1 to 0.Then when its time to make the code, i simply use a for loop to spit out the array in the way i want.

I understand that i could perhaps create a class for the pictureboxes, but i dont know how to, since ive never dealt with them, and i dont understand any of the guides and tuts.how to use a class so that i could add and change the properties of multiple dynamically created pictureboxes, but also change the value of an array created with the picturebox, when clicked?

i need all of this to be done however without adding or including any additional libraries or anything to visual basic as it will be graded on school computers.

Access Objects On A Dynamically Created UserControl An A Dynamically Created Tab Page?

Dec 5, 2011

I can usually find the answers to most of my questions via the Google Gods, but not this time.I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.

On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection. I can't get my head around how to access the objects on the newly created tabpage.

What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it!

Dynamically Created Label Data Not Displaying?

May 26, 2010

I'm programatically creating labels in programatically-created panels, and have run into an issue--the label's information isn't completely showing! COnsistently only the first few characters are consistently displayed. I've tried bringtofront, but it doesn't work at all. And the characters stop well short of the panel barrier--does anyone know what to do about this? I used messagebox.show(labelname.text) to make sure it wasn't working properly, and sure enough all the characters I want are in the label, but aren't appearing.

As you can see, when I open a program from my menu, a new button will be created with text similar to this, "C:Program ". The button it self will not do anything. How can I create the method at the same time the button it is for is created? Also how can I change the text do that it gives me, for example, CCleaner.exe instead of the whole target path?

VS 2008 : Accessing Objects Created In Code?

Oct 31, 2010

I am trying to access objects created at run time.The following code works IF Options Strict is off. If it is on it indicates "Option Strict On disallows implicit conversions from 'System.Windows.Forms.Control' to 'System.Windows.Forms.TextBox'."

Option Strict Off
Public Class Form1
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim txt As TextBox = Me.Controls("T3")

[code]....

I am having trouble formulating the type conversion.A Second problem I am having occurs when I create a groupbox at runtime and then add the textboxes to the groupbox. I am having trouble drilling down to gain access to the textboxes inside the groupbox.

VS 2008 Accessing The Controls On A Form Which Is Not Created?

Jan 30, 2011

When I try to access the controls of a form which is not yet created (i.e. to modify the contents of a text box , to press a button etc) , I fail , usually without even an error message . I found out that the only way to make my program go right is to take care that the form is first created before I try to access anything on that form . However this means I must use the Show method to create it and then to Hide it , which leads to an instant awful optical effect . I remember back in VB6 there wasn't such a problem ; it seems that in VB6 each time I accessed a control on a not-created form led to the form being created silently . Is there any way I could do that in .NET too in order to access my precious controls ?

Accessing Word Tables Created In Word Templates / Accessing Existing Bookmarks In Word Templates?

Jun 30, 2010

Basically in visual basic 6 I could access word tables in existing templates with the code owordactivedoc.tables(1).select() where owordactivedoc refers to the active word document and tables(1) refers to the first table in the template.Trying the same code in VB 2003 just leads to errors. Secondly how do I access bookmarks or alternatively word variables.Furthermore how do one deploy web.services. For example the current program I am building is for another computer. Simply copying the web service to Inetpubwwwroot dont work because it is not picked up by the Internet Information Services program. I have to create the web service in vb2003 on the other computer change msconfig manually. Copy and paste the existing service vb file in the created folder replacing the empty vb file.

Add Events For Dynamically Created Buttons?

Jan 14, 2010

My process is as follows:I access a database table to determine what questions to ask (20-100 questions).Each question is display along with, possibly, a "done" button.My code to do this is as follows:


If datareader("Who_Second").ToString = lbl_Your_Position.Text Then
Dim b1 As New ImageButton
b1.ID = "btn_second" & datareader("QCC_Q_ID").ToString

[code]....

What I need to do for each button is strip out what the "QCC_Q_ID" is for that button and insert information into another table of the DB.My partial code for this is as follows:

Sub btn_done_clicked(ByVal sender As Object, ByVal e As System.Web.UI.ImageClickEventArgs)
Dim MyDate As Date
Dim QCC_Q_ID, Position As String

[code]....

Two problems:1. My sub is never being called, so I can only assume that my "addhandler" is not working.2. QCC_Q_ID = e.ToString.... That doesn't seem right - is it? What I need to do is get the name of the button (btn_second13) and get just the number out of that (13). Is there any easier way to keep track of that ID?
